Abstrakt: The purpose of this study was to reveal the ankle joint moments, arising from different shapes and mechanics of plantar flexion control during walking. The subject was 52-year-old man who was not limited in lower limb range of motion. Peroneal nerve palsy was temporarily induced using a regional anesthetic by artificial means. The orthoses were P-AFO (T85) with Tamarach joint (L85), P-AFO with a hydraulically controlled joint (GSD) and a shoehorn shaped without joint P-AFO (SHB). We compared the walking among these orthoses and healthy walking and drooping foot (DF). In the early stance phase, a big moment occurred with SHB and T85 compared with healthy walking, and GSD and DF were at the same level. Therefore, we think an auxiliary moment rarely occurred with GSD. The results suggest that to bring out the joint function to its maximum, it is important to convey the moment to the foot joint by a reaction force by means of a foot plate covering from the heel to the MP joint.
